Abstract

DYNAMOMETER MACHINE TO DETECT THE MAGNITUDE OF A LOAD APPLIED TO THE SAME. IT CONSISTS OF A PLATE OR TRAY (17) THAT CAN MOVE VERTICALLY FROM ITS UNLOADED POSITION TO A LOADED POSITION; OF A PAIR OF HORIZONTAL BEAMS (19A, 19B) COUPLED IN THE PLATE (17), SUCH THAT FOUR FORCES ARE EXERCISED VERTICALLY DOWN AT THE APPLICATION OR COUPLING POINTS; AND OF ELASTIC COUPLING MEMBERS, EACH ONE OF WHICH ALLOWS THE DISH (17) TO REST ON THE RESPECTIVE HORIZONTAL BEAM AND TRANSMIT A STRENGTH THAT DEPENDS ON THE COORDINATE OR THE LOAD; AND OF SPRINGS TO PREVENT THAT THE PLATE (17) IS ACCIDENTALLY SEPARATED FROM THE REST OF THE SCALE AND TO KEEP THE HORIZONTAL BEAMS FITTED IN THEIR PLACE.
